PA1230R Integrated Amplifier At a time when many manufacturers are using microprocessor technology to bury functions below several software layers so you need to have an owners’ manual close at hand if you want to access them, T+A has delivered an amplifier where each function has its own control, properly and clearly labelled, on the front panel. This necessarily means there are quite a few knobs and buttons, but rarely has an amplifier been so easy to use. This is especially the case because the PA1230R is one of the very few amplifiers available that allows you to adjust bass and treble individually for the left and right channels. Learn More

Audio Research VS110 unused since 2014 Given the enthusiastic response to the appearance and sonic peformance of the VS55, you will be happy to know that a more powerful version of this remarkable amplifier is now available: the VS110, rated at 100 WPC. This brings vacuum-tube musicality as only Audio Research can do it to a new power level and price. The chassis, circuit layout and feature set of the VS110 are almost identical to the VS55, but scaled up to accomodate the greater power output. The chassis itself measures 17 ½" W by 19" D, and features an anodized, natural-finish top plate labeled with tube location/type, output-tube bias access points and the inset Audio Research logo. The chassis front holds a rocker-style power switch and green LED "on" indicator. The chassis rear provides the 0-4-8 ohm 5-way binding posts, voltmeter test points for setting bias, a 12V in/out trigger and a detachable 14-gauge A.C. line cord with IEC socket. There are two matched pair of 6550C output tubes in each channel, fed by two 6NIP triode driver/followers, which in turn are fed by a single 6NIP input tube. Storage capacity of the bulk power supply is double that of the VS55 and uses the same type of fast, low-ESR Nichicon® capacitors. The simplicity and purity of the audio circuit is a proven performer, but now it can deliver more power for larger speakers in larger rooms. Like the VS55, the VS110 ships in one color /chassis configuration, black with natural anodized top plate. A perforated cage-type cover is optional, and must be ordered as a separate item. The sonic signature of the VS110 is very much like that of the VS55, but with more robust dynamics, greater bass impact and power, and a larger soundstage. With so much similarity between these two amplifiers, choosing the right amplifier is simple. The look, the feature set, the circuit types are identical: it is simply a question of how much power you need or want. The VS110 combines classic tube-amplifier appeal with robust power, genuine musicality and solid value. And don't forget Audio Research's unmatched record for long-term product support - a key measure of keeping customers satisfied, decade after decade. POWER OUTPUT 100 watts per channel continuous from 20Hz to 20kHz. 1kHz total harmonic distortion typically 0.5% at 100 watts, below .05% at 1 watt. Approximate actual power available at "clipping": 120 watts (1kHz) (Note that the actual RMS power output is dependent upon both line voltage and "condition" ie: if power line has high distortion, maximum power will be affected adversely, although from a listening standpoint this is not very critical.)

Krell S-1500 5 Channel Amplifier Black Freshly recapped 5 Channel Amplifier Very Good Condition Original Box We also have a second black unit available 5/24 Based on a rock solid, linear power supply design, the S –1500 is virtually impervious to speaker demand or AC line fluctuations. A 1,500 VA toroidal transformer and robust, 80,000-microfarad array of quick -charging filter capacitors offer enormous energy storage, avail- able in an instant. This supply is designed for massive current delivery while maintaining an ultra-low noise profile. Surface mount technology is utilized in the amplifier channels to achieve the high circuit density required for wide bandwidth performance. Eight high- speed power devices per channel deliver 150 W into 8 Ohms and 300 W into 4 Ohms. The amplifier is stable at any load impedance. Krell Current Mode TM, fully balanced topologies, are utilized for all amplifier channels for the lowest noise and greatest detail retrieval. Class A circuitry is utilized in the input, pre -driver, and driver stages to provide the most accurate signal path. All channels support balanced and single -ended inputs. High quality, 5-way binding posts allow speaker connections via bare wires, spade lugs, or banana plugs. A modular platform provides an upgrade path for the S–1500/3, S –1500/5 and S –1500/6 amplifiers, enabling additional channels to be installed at any time. The base platform includes input and speaker connections for up to 7 channels, making upgrades a simple matter when desired. • 80,000 Microfarads of Filter Capacitance • 12 VDC Triggers • 17.3W,5.7H,19.8D Learn More
